Burgess Clock B is the World’s Most Precise Pendulum Clock and is Made to a 250-Year-Old Design by John Harrison, Longitude Prize Winner and Inventor of the Marine Chronometer
Two-hundred fifty years ago, Longitude Prize-winning clockmaker John Harrison made clocks losing just one second per month. But that wasn’t enough for him: in his later life, Harrison claimed that he could make a wall clock with a then-unheard-of-precision of just one second over 100 days! And 250 years later, it turns out he was right.
